Jakarta: A powerful earthquake rocked remote eastern Indonesia on Tuesday, killing a teenage boy who fell into a river as he fished and damaging several buildings.

The 7.0-magnitude quake struck inland in a mountainous area of Papua in the early hours, almost 250 kilometres (150 miles) west of the province`s capital Jayapura, the US Geological Survey said.

"The quake was felt very strongly for four seconds," said Indonesian disaster agency spokesman Sutopo Purwo Nugroho. "Residents panicked and rushed out of their homes."

Rescuers were still trying to reach the area closest to the epicentre in Memberamo district, Nugroho added.

An AFP reporter in Jayapura said weak shaking was felt in the city for a few seconds.

One house collapsed and another was partially damaged in Kasonaweja city, not far from the epicentre, while patients were evacuated from a hospital after its walls cracked, said local disaster agency official Yonas Taudufu.

A 15-year-old boy fell into a river where he was fishing and drowned when the quake hit, he said. Local people later recovered his body.

A 50-metre (160-foot) crack also appeared in a road.

Indonesian authorities and the Pacific Tsunami Warning Center said there was no threat of any tsunami.

A huge undersea quake in 2004 triggered a tsunami that engulfed Aceh province on western Sumatra island, killing more than 170,000 people in Indonesia and tens of thousands more in other countries with coasts on the Indian Ocean.
